Re: Brake sensor light
You must check the layout first if the layout is ok then trace from the dash boards connection and you will know what wrong with the dash board lighting system,.after that contact your auto eletrician to re-connect the wires in the dash board.thank you

What dash lights come on? if its the brake or ABS lights that means your brake pads need to be changed, in some brake pads there is a sensor that also has to be replaced if you have gone too far into the rotor.
some vehicles have a sensor that attaches to the brake pads and when they wear to the point that the sensor touches the rotor, it'll wear the plastic off the sensor and touch the metal inside to trigger a replace brakes light on your dash. im not familiar with the prius's system, but if you had a wire going to your brake pads, you'll need to replace it. once the sensor is triggered, it's no good anymore.
As the brake pads wear, the brake pad wear sensor contained in the brake pad contacts the brake rotor. This causes the sensor to fail. When a pad wear sensor fails it opens the ground circuit of the pad wear warning light system causing the pad wear warning light to illuminate. Perform normal brake service to correct this condition and be sure to replace the brake pads with pads containing wear sensors. Once the brake pads and wear sensors are replaced, reset the brake pad warning system by turning the ignition switch to the "on" position. As long as continuity to ground exists through all the brake pad wear sensors the system should reset and the pad warning light in the dash will go out. If the pad warning light does not go out, a check of the pad warning circuit for an open circuit condition or poor ground must be performed.
this sounds like the brake pads may have worn down and the sensors have lit the warning light on the dash, check the brake pads and if the thickness of the pad is at about 3mm then a new set of pads and sensor will be required
Raise the hood.....find the brake fluid resevoir ( usually up by the windshield/firewall area...drivers side) It will look like a clear or opaque colored plastic oblong container...not much larger than a soap dish, only deeper. Find the "full mark" on the side of vessel, and make sure brake fluid level is at the mark. You can find DOT3 brake fluid in convenience stores, gas stations and even grocery stores. Dont overfill...
check the brake fluid level, if its low the light will be on. Usually when the brake pads wear down the fluid will become low and thats about the time to change the pads. You should be able to add some fluid though and be ok for a bit. If you hear any funny sounds like grinding or squicking (sp) then its time for brakes.
